<P>PROBLEM TO BE SOLVED: To provide a practical cooler, a heater and a water heater suppressed in the consumption of fossil energy. <P>SOLUTION: A composite device includes: a hot water storage tank 11 including a latent thermal storage body; a refrigerating cycle circuit for generating hot water from the heat of outside air by using midnight electric power (heat is collected by a heat exchanger 33 and hot water is generated by a heat exchanger 37); a refrigerating cycle circuit for promptly generating hot water from the heat of outside air (heat is collected by the heat exchanger 33 and hot water is generated by a heat exchanger 38); a plurality of refrigerating cycle circuits for generating hot water from heat in the hot water storage tank 11 (heat is collected by a heat exchanger 37A or 37B and hot water is generated by the heat exchanger 37); a refrigerating cycle circuit for generating hot water from waste heat during cooling (cooling is performed by a heat exchanger 53 and heat is exhausted by a heat exchanger 57); and two circulating flow passages for radiating solar heat by a heat exchanger 67 and heat exchangers 67, 69B. The composite device further includes a drain port 19 between the heat exchangers 37, 57. Thus, the composite device efficiently generates hot water by using midnight electric power, solar heat and waste heat during cooling etc., efficiently performs cooling and heating and has a small size, a large heat capacity and a simple and inexpensive structure. <P>COPYRIGHT: (C)2011,JPO&INPIT |
